You can:

• Delete folders <.settings>, , , and files <.classpath>, <.project> and .

• Delete your project in Eclipse (right button, ) without deleting the source files.

• Create a new Android project and select from your previous sources.

• Import external libs, if needed in the build path.

It should solve this annoying problem.
